Having practised on Dublin's Capel Street, Mr Lynn was struck off more than seven years ago.

While there is no extradition treaty between Brazil and Ireland, a temporary bilateral agreement was struck, meaning Mr Lynn can be extradited - and that if he is convicted and jailed here his time served in a Brazilian prison will be discounted.

Last month, it emerged that the amount paid out in claims by the Law Society to compensate clients for solicitors who default rose 29pc to €3.67m in 2014.

The most high-profile case in recent years was that of Mr Lynn, who cost his fellow professionals €2.6m in compensation paid out.
